Of course, Lei Dong knew that with his current strength, he probably wouldn't be able to break that seal. Although Primal Chaos True Essence was the root of all True Essence and could manifest all spirits, without inherent cultivation and understanding of certain attributes, true manifestation was impossible.

For instance, logically, Primal Chaos True Essence could transform into Blazing Fire True Essence, theoretically allowing the casting of Extreme Yang True Fire or even Solar True Fire. However, because Lei Dong himself had an extremely weak understanding of the Laws of Fire, at most he could only unleash Three Yin True Fire or Three Yang True Fire. Using such flames against cultivators of the same rank was purely a joke; it wouldn't even scorch one of their hairs.

Similarly, although Lei Dong understood the Laws of the Netherworld deeply, he had not yet reached a high or ultimate level of comprehension. Consequently, the Netherworld Ghost Qi transformed from his Primal Chaos True Essence was nowhere near potent enough to undo the seal placed by Fairy Bibo.

Throughout history, the one who grasped the Laws of the Netherworld the most profoundly was likely the Death God. Many Netherworld-based spells and cultivation methods were first conceived and practiced by that elder. Regrettably, the Death God’s whereabouts have always been an enigma throughout history. But Lei Dong, who understood many of the secrets, estimated that the Death God had probably met his demise long ago. Otherwise, there would have been no need to leave behind a successor of a later generation, the King of the Underworld.

Naturally, the King of the Underworld also possessed an extremely high and deep understanding of the Laws of the Netherworld, but the King of the Underworld had also met a tragic end long ago. As for the Ghost Emperor, his cultivation was not in the Netherworld lineage, but in the Primal Chaos Art. The Primal Chaos Art manifested myriad forms and possessed infinite power, which naturally dictated that the Demon Emperor could not achieve any great depth in comprehending the Laws of the Netherworld.

In fact, among the third inheritance Lei Dong received, the knowledge regarding the Netherworld lineage shared by the Demon Emperor was genuinely sparse. In some areas, his understanding was even slightly inferior to Lei Dong’s. This was hardly surprising. No one is perfect. The Demon Emperor Yan Chixing primarily cultivated the Laws of Annihilation and the Laws of Indestructibility—one for offense, one for defense—while also dabbling in some True Word Arts. Regarding other Laws, he had some exposure, but none reached the level of penetrating heaven and earth.

Now, it seemed there was only one path left: to frequently study the Laws of the Netherworld in his free time, striving to break the seal within the King of the Underworld Banner as soon as possible. As for the mournful expression of Ming Ji, Lei Dong truly couldn't bear it and was too lazy to pay her any more attention. He genuinely couldn't comprehend what kind of environment could nurture such a peculiar personality in her.

As for Mei Xiang, Lei Dong once again infused her with some pure Netherworld Ghost Qi to help her recover some vitality. After offering kind words of comfort, he promised to find suitable materials to personally refine a puppet for her.

After dealing with his own messy affairs, Lei Dong finally turned his attention to the battlefield.

The battle raging there had reached its most intense phase. Originally, dozens of Void Refinement-level black giants, aided by the green creatures, had gradually gained the upper hand. However, as soon as the Integration Stage Demon King, a high-ranking demon, appeared leading his subordinates, the situation instantly reversed.

Even with the constant healing provided by the green creatures from the rear, the black giants were being destroyed one after another, falling into the void. If the situation continued like this, without any surprises, the black giants would be completely annihilated within an hour or so.

The desire to devour that Integration Stage Demon King grew stronger and stronger. Lei Dong knew clearly that with his current strength, aiming to eliminate that Demon King alone was utter delusion. The only way to achieve his goal was to cooperate with those black giants.

Swallowing a Primal Chaos Spirit Gathering Pill, Lei Dong rapidly replenished the consumed Primal Chaos True Essence. Simultaneously, he summoned the Soldier Storing Pagoda, releasing a continuous stream of Ghost Clan powerhouses and Submerged Dragon soldiers. Fortunately, Lei Dong did not place much value on this Soldier Storing Pagoda seized from Saint Radiance King, so he hadn't refined it with his soul as an overly precious spiritual treasure.

Otherwise, this Soldier Storing Pagoda would likely have been thrown out by that fool Ming Ji to block heavenly lightning. As for the Grotto-Heaven and Blessed Land, although it was refined by Lei Dong's soul, it had mostly been stored within the Primal Chaos Strange Space in recent years, thus escaping disaster. Otherwise, no matter how useful Ming Ji might have been, she would have been refined alive under Lei Dong’s fury.

Lei Dong's original plan was to develop in the Chaotic Star Domain, so the troops kept in the Soldier Storing Pagoda were elites: one thousand elite Fierce Ghost Soldiers and one thousand elite Submerged Dragon Soldiers. These were the direct subordinates Lei Dong selected from the main army, possessing the best aptitude and potential, with loyalty that required no questioning, a core force utterly fanatical about Lei Dong.

Do not underestimate these mere two thousand troops; they contained over one hundred and fifty Nascent Soul Transformation stage powerhouses. The rest were almost all late-stage or peak Nascent Soul cultivators.

Furthermore, Lei Dong summoned another hundred puppets at the Nascent Soul Transformation stage from his storage ring. Although most were bronze puppets at the early stage of Nascent Soul Transformation, they were personally refined by the King of the Underworld, giving them extraordinary power.

Moping was also summoned by Lei Dong, and the sharp-witted spirit was tasked to act as the general for those Nascent Soul Transformation puppets, granting him command authority.

Following this, Lei Dong summoned Lei Hu, Gui Ci, Gui Ming, and others, instructing them to participate in the battle. Flowers raised in a greenhouse never grow tall. Although Lei Dong would expend great effort cultivating them, it did not mean he would shield them from dangerous warfare.

With Lei Dong's command, the entire army began to charge toward the battlefield, rushing toward the enemy in the void like a swarm of meteors. Over two thousand troops, the weakest being late-stage Nascent Soul cultivators. In terms of pure quality, they held an edge over that Demon Race army. Their only deficit was in numbers.

Of course, they were also slightly weaker in terms of Void Refinement level strength. Therefore, Lei Dong activated the Universal Sun Concealment Art, condensing his aura to resemble that of a late-stage Nascent Soul Transformation expert. He led the charge, heading straight for a Void Refinement stage powerhouse of Asura origin.

At this moment, Lei Dong’s cultivation had advanced by leaps and bounds after enduring the Void Refinement Tribulation, stepping into the middle stage of Void Refinement due to various incredible transformations. His Primal Chaos True Essence was incomparably profound. But under the subtle use of the Universal Sun Concealment Art, he only revealed the aura of a late-stage Nascent Soul Transformation expert.

The Asura Clan was a peculiar race. Male Asuras were ugly and ferocious in appearance. But female Asuras were exquisitely beautiful.

That male Asura was clad in a suit of pitch-black, extraordinary armor, leading a contingent of subordinates of no small strength behind him. Seeing Lei Dong recklessly charge toward him alone, the male Asura sneered inwardly and met the charge directly, not giving Lei Dong a second thought.

Netherworld Nether.

Lei Dong unleashed his signature ability. Dense black Ghost Qi danced wildly, instantly enveloping the battlefield spanning dozens of miles.

"A petty trick, daring to display it before me?" The Void Refinement Asura sneered, darting into the thick Ghost Qi. He grasped a giant axe, bringing it down in a single swing: "Disperse!"

The axe conjured a massive projection, carrying the force as if ready to cleave the heavens and earth. Where the energy blade passed, the space was torn open by a huge rift. The surrounding Netherworld Ghost Qi vanished without a trace.

If Lei Dong were truly only a late-stage Nascent Soul expert, he would naturally be no match for him. But now, he was far from his former self. Even if he encountered Ji Shuangshuang, the young master of the Vermilion Bird Clan, again, going all out would make defeat absolutely impossible; his strength could be called terrifying.

His figure merely flickered slightly, darting into the void without any trace of fiery energy. In an instant, accompanied by a faint spatial fluctuation, he appeared silently behind the Void Refinement Asura and struck out with a palm.

A ten-zhang long, pitch-black demonic palm, carrying an overwhelmingly domineering aura, slammed toward the Asura as if swatting a fly.

At such close range, and given that Lei Dong’s current techniques would inevitably incorporate some understanding of spatial laws, the movement appeared slow but was actually fast. The unsuspecting Asura was struck hard by the palm. The Asura was sent flying over a hundred zhang, his dark armor instantly showing numerous cracks, blood spurting violently from his mouth. His face was a mix of shock and rage, clearly showing disbelief.

That palm strike from Lei Dong was the Netherworld Palm from the Netherworld series of spells, having decent power, though he didn't use it often. The ability to unleash such power was due to several factors. Firstly, Lei Dong himself was already a middle-stage Void Refinement expert; any technique executed by him carried immense power.

Secondly, fighting within the Netherworld environment he had created granted a significant power amplification to all kinds of Netherworld spells. Finally, and most importantly, in the third inheritance, Lei Dong had received much insight and understanding concerning the Laws of Annihilation and Indestructibility. The Demon Emperor had integrated his comprehension of these Laws into the Emperor Demon Seed and passed them on to Lei Dong upon his death.

One could say the Demon Emperor was perhaps the person Lei Dong should be most grateful to in his life; the legacy left to him was incredibly rich.

Lei Dong had directly delved deeply into the Laws of Annihilation and Indestructibility through this inheritance. Lastly, he integrated a trace of the Law of Annihilation into his techniques, greatly increasing their power. Of course, even after receiving the inheritance, it was impossible to become immensely powerful instantly. Lei Dong still needed to constantly integrate and grasp his inheritance through actual combat to ultimately transform them into his own abilities.

All these factors combined resulted in the tremendous power displayed by Lei Dong's seemingly ordinary Netherworld Palm strike.

Strike while the iron is hot; press the advantage while victory is certain. Lei Dong employed the Ghost Shadow Evasion, moving truly like a phantom, especially within this Netherworld environment where his tracks were impossible to trace. The surging Netherworld Ghost Qi transformed into sharp arrows, shooting toward the Void Refinement Asura like a dense volley of heavenly shafts.

Unable to resist, just as the Void Refinement Asura was about to deploy a secret technique to flee and save his life, a giant ghost claw, appearing to erupt from the deepest hell, seized him tightly.
